Texas, May 20- Average retail gasoline prices in Texas have risen 3.3 cents per gallon in the past week, averaging $3.42/g yesterday, according to GasBuddy's daily survey of 13,114 gas outlets in Texas.

Including the change in gas prices in Texas during the past week, prices yesterday were 8.5 cents per gallon lower than the same day one year ago and are 7.3 cents per gallon higher than a month ago. The national average has increased 16.6 cents per gallon during the last month and stands 3.0 cents per gallon lower than this day one year ago.

"The last seven days have delivered some shocks at the pump for motorists in the nation's Midwest," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "I don't believe I've ever seen gasoline prices in the Midwest surpass California- areas of Nebraska, Minnesota, Oklahoma, North and South Dakota, and Kansas- have done that. Gas price records in these areas aren't being quietly replaced, they're being blown out of the water. I don't believe I've ever seen such crazy trends in gasoline prices occur all at one- prices spiking in one area, falling in another, and holding steady in others. What we're seeing today is certainly rare," DeHaan said.
